Daim kab xev
Txoj kab uas hla feem ntau cuam tshuam rau qhov ntev tshaj plaws ntawm ib qho drip daim kab xev khiav ua ntej siab thiab ntws sib xws pib poob.
● 5/8 "(16mm): Qhov no yog txoj kab uas hla tshaj plaws thiab ntau yam. Nws ua haujlwm zoo heev rau kev khiav mus txog 400-600 ko taw (120-180 meters).
● 7/8 "(22mm) thiab loj dua: Cov kab uas hla no yog rau kev ua liaj ua teb loj -. Lawv tso cai rau kev khiav ntev heev, feem ntau tshaj 600 ko taw, txo qhov xav tau ntxiv sub- cov kab tseem ceeb hauv cov teb loj, qhib.
Emitter Spacing
Qhov no ntsuas qhov kev ncua deb ntawm cov dej tawm ntawm cov kab xev. Lub hom phiaj yog xaiv qhov sib nrug uas tsim kom muaj cov kab nrib pleb uas txuas ntxiv mus raws cov kab cog.
● 4-8 ntiv tes (10-20 cm): Qhov sib nrug ze no yog tsim nyog rau cov av xuab zeb uas muaj dej tsis zoo rau sab nraud. Nws kuj tseem zoo rau cov qoob loo cog qoob loo zoo li carrots, dos, qej, thiab nplooj ntsuab.
● 12 ntiv tes (30 cm): Qhov no yog txhua yam - lub hom phiaj, qhov sib txawv tshaj plaws. Nws yog qhov zoo tagnrho rau feem ntau cov kab qoob loo thiab zaub, suav nrog txiv lws suav, kua txob, pob kws, squash, thiab taum.
● 18-24 ntiv tes (45-60 cm): Qhov dav dav ua haujlwm rau ob qhov xwm txheej tseem ceeb: cov nroj tsuag dav dav zoo li taub taub lossis melons, lossis hauv cov av nplaum hnyav uas cov dej sib kis ntau tom qab hauv qab ntawm qhov chaw.
Flow Rate (GPH lossis LPH)
Flow rate qhia cov dej ntim xa los ntawm txhua tus neeg emitter ib teev. Qhov kev xaiv no yog qhov tseem ceeb txuas rau koj cov av infiltration tus nqi thiab koj cov nroj tsuag cov dej tshwj xeeb.
● Tsawg Flow (0.1-0.25 GPH): Tus nqi no ua haujlwm zoo tshaj plaws rau cov av nplaum hnyav uas nqus dej maj mam. Nws kuj tseem nyiam rau thaj chaw sloped kom tiv thaiv dej hauv pas dej thiab dej ntws.
● Nruab Nrab Flow (0.4-}0.6 GPH): Ib qho kev xaiv zoo tagnrho rau cov av loamy thiab ntau yam nroj tsuag. Nws muab qhov sib npaug zoo ntawm daim ntawv thov ceev thiab av nqus.
● High Flow (0.8-1.0 GPH): Tus nqi no yog siv rau cov av xuab zeb heev uas ntws sai sai, xyuas kom cov dej mus txog thaj tsam hauv paus ua ntej yuav tob heev. Nws tuaj yeem ua haujlwm rau lub thawv loj hlob lossis cov qoob loo uas xav tau dej siab heev.
Ⅲ. Layouts rau ntau qhov chaw ib puag ncig
Kev siv cov kev qhia tshwj xeeb no kom raug yuav tsum muaj kev npaj tsim kom haum rau koj qhov chaw cog qoob loo.
⒈ Qhib teb thiab kab qoob loo
Rau loj -tej teb irrigation thiab kab qoob loo irrigation, efficiency thiab uniformity yog qhov tseem ceeb tshaj plaws. Qhov kev teeb pom kev zoo tshaj plaws yog siv ib kab ntawm drip irrigation daim kab xev rau ib kab qoob loo. Rau cov txaj dav heev lossis cov qoob loo uas muaj cov hauv paus hniav dav, ob kab ib kab, sib nrug li 12-18 ntiv tes, yuav tsim nyog.
Subsurface Drip Irrigation (SDI) yog cov txheej txheem siab heev uas daim kab xev tau faus 6-12 nti tob. Qhov no tiv thaiv daim kab xev los ntawm kev puas tsuaj, txo evaporation mus rau zero, thiab tso cai rau kev ua haujlwm xws li tilling thiab txau yam tsis muaj kev cuam tshuam rau lub cev. SDI yuav tsum muaj daim kab xev hnyav (15 mil lossis ntau dua) kom tiv thaiv cov av puas thiab tiv thaiv cov hauv paus hniav. Xaiv qhov zoo specs nyob ntawm cov qoob loo loj hlob.

⒉ Raised thiab Vaj txaj
Cov txaj txaj txaj tsim ib qho chaw tshwj xeeb. Lawv muab cov kua dej zoo heev. Cov ciam teb uas tau hais tseg kuj cuam tshuam rau kev tsim qauv.
Rau cov txaj me me, feem ntau tsawg dua 8 feet ntev, "loop design" ua haujlwm zoo heev. Daim kab xev drip khiav mus rau ib sab ntawm lub txaj, loops nyob ib ncig ntawm qhov kawg, thiab rov qab mus rau sab nraud, txuas nrog cov khoom siv ntawm ob qho kawg. Qhov no equalizes siab thiab xyuas kom meej heev txawm watering los ntawm pib mus rau tag.
Rau cov txaj loj, "daim phiaj" lossis "nas" qauv zoo dua. Khiav ntau lub laterals hla lub txaj dav, sib nrug ntawm 12 txog 18 ntiv tes sib nrug, txhua qhov txuas nrog ib qho khoom siv header khiav ntawm ib sab.
Qhov nruab nrab ntws tus nqi (ib puag ncig 0.5 GPH) nrog 12-inch emitter spacing yog txhim khu kev qha rau feem ntau cov zaub sib xyaw ua ke. Lub 8-10 mil phab ntsa tuab muab cov kav ntev txaus rau ob peb lub caij.Qhov sib zog, zoo-airated av nyob rau hauv tsa txaj ntws sai sai, yog li koj yuav tsum tau dej ntau zaus tab sis rau lub sij hawm luv.
⒊ Pots thiab Thawv
Kev cog qoob loo yuav tsum muaj micro- txoj kev ua dej. Standard drip daim kab xev feem ntau tsis tsim nyog rau ib tus neeg lub lauj kaub vim nws qhov chaw ruaj khov emitter thiab tus nqi ntws siab, uas tuaj yeem ua rau dej nyab lub thawv me me.
Qhov zoo tshaj plaws layout siv 1/4-inch tis tubing (feem ntau hu ua "spaghetti tubing") raws li lub ntsiab xa khoom kab, branching tawm ntawm ib tug loj 1/2-nti los yog 3/4-inch mainline. Los ntawm cov tubing me me no, koj tuaj yeem tso ib tus neeg emitters raws nraim qhov xav tau.
Kev xaiv emitter yog qhov kev txiav txim siab tseem ceeb tshaj plaws rau cov lauj kaub.
● Cov lauj kaub me me (<5 gallons): Use 0.5 GPH or 1.0 GPH pressure-compensating "button" drippers. A single dripper placed at the plant base is usually enough.
● Large Pots (>5 nkas loos): Siv cov drippers kho tau uas tuaj yeem teeb tsa los ntawm cov drip qeeb mus rau cov kwj me me, lossis siv ua ntej - ua drip rings. Lub nplhaib drip yog ib lub voj voog ntawm tubing nrog ob peb lub qhov hluav taws xob me me uas faib cov dej sib npaug ntawm tag nrho cov av saum npoo, uas yog qhov tseem ceeb rau cov ntim loj.
⒋ Sloped Terrains
Kev ywg dej rau ntawm txoj kab nqes qhia txog kev sib tw ntawm lub ntiajteb txawj nqus. Hauv cov txheej txheem txheej txheem, cov dej siab yuav siab dua nyob rau hauv qab ntawm txoj kab nqes dua nyob rau sab saum toj, ua rau muaj dej ntau dhau ntawm qhov kawg thiab underwatering ntawm qhov siab kawg.
Lub hauv paus ntsiab lus layout yog: ib txwm khiav drip daim kab xev laterals raws lub contour ntawm txoj kab nqes, tsis nce los yog nqis. Qhov no ua rau txhua tus kab mob sib txawv, txo qis kev hloov pauv raws nws qhov ntev. Cov kab hluav taws xob tseem ceeb tuaj yeem khiav nce lossis nqis nqes los pub cov theem laterals.
Lub emitter specification yog qhov tseem ceeb sib npaug. Koj yuav tsum siv Pressure Compensating (PC) emitters lossis PC drip tape. PC emitters muaj ib qho ua tau - nyob rau hauv diaphragm uas tswj cov dej tso tawm, xa cov dej ntws zoo ib yam thoob plaws ntau qhov kev kub ntxhov. Qhov no ua kom cov nroj tsuag kawg ntawm kab tau txais cov dej tib yam li thawj zaug. Tsis tas li ntawd, siv cov emitters qis qis (0.1-0.25 GPH) kom cov av siv sij hawm nqus dej, tiv thaiv dej ntws thiab yaig.
Ⅳ. Advanced Strategies
Tshaj li cov txheej txheem yooj yim, tus kws tshaj lij- theem tsim tau txiav txim siab txog qhov sib txawv ntawm ib puag ncig. Cov tswv yim no daws cov teeb meem nuanced thiab txhawb nqa qhov system zoo mus rau qhov zoo.
⒈ Kev cuam tshuam ntawm Av Hom
Av muaj pes tsawg leeg yog kab tias ib qho tseem ceeb tshaj plaws ntawm ib puag ncig cuam tshuam rau kev tsim cov dej ntws. Yuav ua li cas dej txav mus los ntawm cov av-tus "wetting pattern"- cuam tshuam ncaj qha rau qhov zoo tshaj plaws emitter spacing, flow rate, thiab watering schedule.

Txoj kev "lub voj voog thiab ntub dej" rau cov av nplaum yuav ua haujlwm rau lub sijhawm luv luv (piv txwv li, 30 feeb), tig tawm rau ib teev kom tso dej rau hauv dej, thiab rov ua dua. Qhov no tiv thaiv nto pooling thiab dej ntws.
⒉ Tsev cog khoom thiab sab hauv tsev loj hlob
Lub tsev cog khoom muaj kev tswj hwm ib puag ncig, ua kom cov dej ntws tawm ib qho cuab yeej muaj zog heev. Uniformity yog qhov tseem ceeb rau cov qoob loo zoo ib yam.
Cov txheej txheem layout zoo
⑴ Ib leeg -Line Layout
● Muab ib txoj kab drips rau ntawm txhua kab kab, li 1-2 ntiv tes ntawm cov stems.
● Qhov no ua haujlwm zoo tshaj plaws rau ib kab ntawm cov qoob loo xws li txiv lws suav, dib, thiab kua txob.
● Nws maximizes efficiency ntev, nqaim txaj nrog cov kab ntshiab.
⑵ Ob chav -Line Layout
● Khiav ob txoj kab sib txuas ua ke hauv ib lub txaj dav, sib nrug ntawm 12-18 ntiv tes.
● Txoj kev no ua haujlwm zoo tshaj plaws rau cov txaj dav (30 ntiv tes lossis ntau dua) nrog cov kab cog staggered.
● Nws ua kom cov dej noo nyob thoob plaws lub txaj dav. Peb pom qhov no ua rau muaj txiaj ntsig zoo rau kev cog qoob loo ntawm cov nplooj ntsuab vim nws tiv thaiv qhov chaw qhuav hauv nruab nrab ntawm lub txaj.
Qhov chaw tswj hwm no zoo meej rau automation. Cov timers yooj yim tuaj yeem tswj cov sij hawm ywg dej, kom tau txais txiaj ntsig zoo, txuas cov kab ke rau cov av noo noo sensors. Cov sensors no muab cov ntaub ntawv - lub sijhawm tiag tiag, ua rau cov dej ntws tsuas yog thaum qhov nruab nrab loj hlob mus txog qhov tshwj xeeb qhuav.
Greenhouses kuj ua kom muaj txiaj ntsig zoo ntawm fertigation. Los ntawm kev siv cov tshuaj chiv, cov khoom noj ua kua tuaj yeem xa tawm tau zoo thiab ua tau zoo los ntawm kev tso dej.
⒊ Hybrid Irrigation Systems
Hauv qee qhov toj roob hauv pes, ib hom kev siv dej tsis yog qhov kev daws teeb meem zoo tshaj plaws. Ib qho kev sib xyaw ua ke, uas sib xyaw ua ke nrog lwm txoj hauv kev zoo li micro-sprinklers, tuaj yeem muab txoj hauv kev zoo dua thiab ua tau zoo.
Txau rau Lub Vaj txaj, Micro-sprinklers rau av npog: Hauv toj roob hauv pes nrog cov txaj txaj thiab thaj chaw loj ntawm qis- cog hauv av, qhov no yog ib qho zoo tagnrho ua ke. Siv cov ntaub nplaum zoo rau cov kab thiab qis - ntim micro-sprinklers los npog qhov dav, ntom ntom ntawm cov av npog zoo dua li cov ntaub nplaum ua tau.
Sprinklers rau germination, Drip rau kev loj hlob: Nyob rau hauv ib tug loj teb, tsim me me noob yuav nyuaj nrog drip daim kab xev. Ib lub tswv yim kev tshaj lij yog siv cov dej siv nyiaj siv ua haujlwm ib ntus kom ntseeg tau tias muaj kev loj hlob thoob plaws hauv cheeb tsam. Thaum cov yub tau tsim, lub drip system tau qhib rau lub hom phiaj, dej kom zoo rau lub caij nyoog loj hlob.
Ⅴ. Xaus
Tus yuam sij rau kev tswj cov dej ntws tawm tsis yog hais txog kev yuav khoom ua ntej - ntim khoom. Kev vam meej yog los ntawm kev nkag siab tias dej coj li cas hauv koj cov av, cov kev xav tau tshwj xeeb ntawm koj cov nroj tsuag, thiab kev txwv lub cev ntawm koj thaj av. Txawm hais tias koj tab tom npaj drip irrigation rau qhib daim ntaub ntawv los yog teb irrigation rau me me, drip irrigation tsim yog ib tug system ua nyob rau hauv precision.
